Ed Spencer promised to include a desktop example in ExtJS 4.0. And yes he did. Very nice. Now I tried to migrate the Desktop from ExtJS 3.3.1 into ExtJS 4.0. In the ExtJS 4.0 HTML example 1 file is used that combines all *.js files. This file is minified. Not all javascript files in the classes.js are present as separate unminified files. Now its impossible for me to migrate the desktop.

Please mister Spencer put the missing unminified files or the unminified classes.js in the example Desktop.

Thanks

I'll ask Don (who wrote the new desktop) to provide unminified files for the next release

how to migrate the the >itemTpl: < config for Panels.

how to migrate the the >itemTpl: < config for Panels.

Hi,

i have a custom Desktop built under Ext 3 which uses customized Panel-Tab's. The customizing is done with the >itemTpl: < config for the panel. This config-Option does not longer exist in ExtJs 4. How to migrate it?

There is no editable property on the Column - or if there is, the documentation makes no mention of one.?

I need to loop around all the rows and columns in a grid and if the fields are editable, I want to validate them. The methods I was using took row and col params.
How can I translate this into the v4 way of doing things, where getEditor takes a record and a default field? I have to say, I am really struggling with converting to v4 - the migration guide seems rather...lacking, so it's only by hunting around and guessing and trying things out that I'm making any progress

Problems setting tree node icons

Problems setting tree node icons

I'm in the process of converting my app from V3 to V4 - so far, thanks to the webcasts and compatibility layer, this has gone pretty smoothly. However, I've now tried to get my tree up and running and I'm stumped (no pun intended!).

Previously my tree used a TreeLoader to get the tree data from the server, and once this was complete, the TreeLoader's 'load' event was used to set the style of the node to make it use the correct part of a sprite as its icon:

Now, in version 4, it appears that the TreeLoader no longer exists, so I've moved to using a
'Ext.data.TreeStore'. This returns me the data for the tree and the tree itself is created, however I can't see how I can get access to the individual nodes to set their CSS style (the 'load' event of a TreeStore doesn't seem to contain the node).
